To all whom it may concern} Y Be it known that I, PERRY resident of Coraopolis, in the county of Allegheny and. State of Pennsylvanla, have invented certain new and useful Improvements in Draft-Rigging, f whi'ch thefollowing is aspecification. p p p This invention relates to improvement n draft rigging for cars and has for its object to provide a tandemrigging of double the ordinary capacity, or one in which I am enabled to utilize two sets of springs in each half ofgtherigging. The invention consists through the line bb of Fig. 3,-butwith the longitudinal sills and; their abutments made separate instead of integral. 7

Figs. 6, 7., 8 and 9;are perspective views of the various partsdetached.

Referring now to the details of'the-drawings by numerals: 1 designates the-ordinary end sill of a. car and 2 and 3 designate the draft irons or the intermediate sills. 4: designates. the shank of the ordinary draw bar and 5 and (iv-designate a pair of side bars which are normally adapted to move backward and forward with the coupler parallel with the said sills 2 and 3 ,,the front ends of the side bars 5 and 6 being secured tothe shank of the draw bar upon opposite sides thereof; The forward ends of said plates 5 and 6 are provided with recesses 8 and 9, the top. recesses SI of each sidebar being adapted *to receive the ends of a connecting plate 10 which passes over the shank of the draw bar immediately in front of the usual shoulder 11. The recesses 9 at the bottom of the front ends of the sidebars 5 and Y 6v are formed in a peculiar manner so. that Biowr, a 'citi; l zen of the United States of America, and adovej ta-il ends12 and 13 of a securingv plate 1 1 may be inserted through the: opening 9' under a shoulder 15 and after the dove-tail PERRY-BROWN,- or-comoroms; rnnnsrrvsnm; MARGARET mqrnowu nxncua'mx Specification of Letters Patent.

ends 12 and13 are back of-said shoulder the plates are moved upward until the dovetail ends 12 and 13'fit doveetail recesses 16 immed ately over the recesses 9. After the securing? platel i is thus placed in position;

a third plate 17 isslipped in the recess 9'.

under the shoulder 15 and a cotter oriothei securing means ispassed througlrcoincid-j ing'openings in gs18 and ia-rheiu 18 projecting from the-plate 1 4: and thelug, v

19. from the plate 17. The-securing. plate 14;

passes under the shank of the draw bar immediately in front of the ordinary shoulder 20', as seen in Fig. 2'. Thus the two plates 10 and 14 co-act with the shoulders 11- "and- .20 of the draw bar shank and hold, the

shank to'the side bars 5 and; 6, At the same time, the dove-tail ends of the securing.

plate 14 prevents said side bars from spreading. The front ends of the side bars 5 and 6 are provided with abutments 22 and 23,

said abutments being reinforced. by horizonzontal walls 2 lrand25 (see Fig.6), The abu tinents. 22 and 23 thus form a means of holding the shank of the draw barbetween the plates 10 and 14 so that the'aforesaid sidebars 5 and 6' and the; draw bar arecom pelled to move together inboth directions. In other words, there is a pocket formed between the plates 10 and-"14 and the abutments'22and 23 within which the shank of the draw bar is immovably secured. The

draftirons or intermediate sills 2 are preferably formed with abutments 25, 26, 27 and 28 cast integrally therewith although, if preferred, said abutments may be formedseparately as indicated at 30in Fig. 5 and riveted to the intermediate sills or draft irons. This is the onlydifferencebetween the construction shown in Fig. 3 and the modified construction shown in Fig. 5.

In addition to the abutments 22 and 23 at the. forward ends ofthe side bars 5 and 6, said bars are also provided. with ribs 32 running substantially the whole" length ofthe. side bars, and substantially at the center of said side bars 1 form lugs 33 and 341 which are preferably cast integrally with said bars, the ribs preventing buckling of the bars. i

' Immediatelybehind the abutments 22 and 23 of the side bars I place the front follower 40 shown in perspective view in Fig. 7, thisfollower having upper lugs 41 and lower lugs 42 which straddle the side bars 51and 6 and co-act with the front abutments cast on the draft irons 2 and 3.- This follower is also provided with side grooves 43 and 44 into which projects the longitudinal ribs 32 of the side bars 5 and 6. This construction not only assists in securing the front follower in position butaids to prevent'the side bars 5 and 6 from'buc'kling'.

. spreading. As an additional safeguard 1 against spreading, a'boltr48 may be'passed through the draft irons'or'sills 2 and 3 and the 'lower 'half of the central block 45, an

opening 49 being provided in the lower half of the block for this purpose. Theicentral block 45 is made of the peculiar construction I shown in Fig. 8 so as to permit theside bars 5 and 6 'and'their integral lugs 33 to pass between the lugs 46 and 47. V of the central block 45 is located a follower,

' V the forward follower being designated 52 and the rear follower 53. 'The forward of these two followers 52 is designed to co-act with the front follower 'hereinbefore referred to and these two followers receive the two setsofsprings 54 and 55. Likewise, the

' follower 53 which has been referred to as being immediately behind the central block is designed to co-act with a companion or rear follower 56, shown in perspective view in Fig. 9, the two followers 53 and 56 designed to receive two sets of springs 57 and 58 (see Fig. 2). This rear follower is preferably made of the peculiar construction shown in Fig. 9 and in addition to having grooves 59 and 60 to receive the longitudinal ribs 32 on the side bars 5 and 6, also has dove tail recesses 61 and 62 which are designed to receive similar shaped lugs 63 and 64 cast on the extreme rear ends of the side bars 5 and 6. This rear follower 56 abuts against two stops and 71, the stop 70 being secured to or cast integrally with the draft iron or sill 2 and the stop 71 with the draft iron or sill 3. These stops 70 and 71 have slots or recesses 72 and 73 to permit the rear ends of the side bars 5 and 6 to be moved backward as the draw bar receives an impact. 4 shown in dotted lines in Fig. 1 and in full lines in Fig. 3. I

On inspection of Figs. 1,2 and 7, it will be seen that the followers have central ribs getheryto prevent} crowding the) springs.

thrust given to the draw bar 4 is received On each side" These recesses 72 and 73. are

which serve the double purpose ofsepa rating the two sets of springs and of forming abutmefntswhen the followers come to- V In operation :iOn an impact the backward 70 firstby the abutment walls 22 and 23 forming the pockets for the shank of the draw bar and is by said abutments transferred directly to the front follower 40, and, through the side bars 5 and'6', to the follower 53. Therefore the followers 40and 53 are shoved rearwardly, compressing both sets of front springs against the followerj52 andboth sets of the rear springs'against the follower 56. On a pull, the draw bar through the v plates 14 and 17, draw the side bars 5 and 6 forwardly and theseside bars draw the rear" follower 56 forward, lcompressing the rearsprings against the follower 53 and simultaneously draw the follower 52 forward,

compressing the other springs against the front follower'40. {During these movements, the central block 45 is anchored between the abutments' 26 and 27 e and therefore receives the thrust in either direction from the followers 52 and 53. On the other hand, the

follower 52 is given its forward movement and the follower 53 its rearward movement by the lugs 32 projecting from the side bars 5 and 6. I

From the foregoing and accompanying drawings, it will be seen that I have con structed a draft rigging of great strength and one which comprisestwo sets of double springs on each side of the central block 45 so that Ihave a double tandem rigging.

It will be obvious that changes and modifications may be madein the form and construction of the various parts without de- 106 the shoulder of the draw bar and bridging the space between said side bars.
